Application filed March 30, 1908. Serial No. 424,104.

To all whom it may concern:

Be it known that we, ALFRED ALBERT MANsnLL, motor mechanic, a subject ofthe King of Great Britain, residing at 26 Portman Mews North, PortmanSquare, in the city and county of London, England, and GEORGE SMITH,motor mechanic, a sub ect of the King of Great Britain, residing at 94Church street, Chelsea, in the county of London, England, have inventeda new and useful Appliance for Preventing Side Slipping of Wheels onMotor-Vehicles and the Like, of which the following is a specilication.

This invention relates to means for preventing side slip on motor carsand like vehicles, and consists in the provision of a flat plate orstrip of material suspended from the frame of the vehicle and lyingclose to the ground and close against the side of the vehicle wheel, insuch manner that as soon as the wheel begins to move sidewise it mountsupon the plate or strip pressing this against the ground.

One form of construction of the invention is illustrated in theaccompanying drawings in which- Figure 1 is a side view and Fig. 2 anedge view of the vehicle wheel to which the invention has been applied.Fig. 3 shows the plate or strip above mentioned, and Fig. 4 is asectional detail View thereof.

. In the form of construction illustrated in the drawings instead of asingle plate of material, a number of separate strips a are employed.The material is preferably chrome leather, raw hide or the like, but itmay be hoo iron or any other material which is su ciently flexible andalso sufficiently strong for the purpose. The strips a are, as shown inFigs. 2 and 4, beveled at the edge I) which is intended to lie closeagainst and even beneath the curve of the tire c of the vehicle wheel.The separate strips a are secured transversely upon a long strap clwhich may also be of chrome leather or the like by means of studs orbolts 6 which, in the example shown, consist of a head carrying twopointed prongs adapted to be bent over after penetrating the material.Naturally this method of fastening may be replaced by any other of theknown methods. The strap d is doubled on itself or has loops f formed atits end by which it is suspended preferably from the bow spring whichsupports the car body. In order that the. device may be readily attachedto or removed from a vehicle, a method of securing it like thatillustrated may well be employed. The loops f are engaged by metal loops9 which are shown in Fig. 2 as having rounded ends but are preferablymade with flat ends so that the strap (Z does not get displaced from itsproper position. These metal loops g are attached by means of a swiveljoint to spring h which latter is joined to one end of a metal plate [7.This link is placed above the spring and beneath it is arranged ashorter plate Z secured to the first by two bolts or the like m passingthrough it and through slots in the lower plate; by this means the platemay be readily adjusted laterally on loosening the bolts m. In order toassist still further in maintaining the strips a in their properrelative position, a metal guide a may be provided. This is preferablyformed from stout wire which is looped at the top and gripped betweenthe plates in, Z, while at the bottom it surrounds the strap (Z. Ifdesired this guide may be permanently connected with the plate 71', soas to move together with them in lateral ad ustment.

At the bottom where the strips a are attached the strap (Z shouldpreferably be reinforced by the addition of another strip 7') behind it,as shown in Fig. 1; or instead a strip of hoop iron may be securedbetween the layers of the strap (I. .l urther, between the strips (1protecting rivets or the like may be secured in the strap, and these projecting between the strips, save some amount of wear between the stripsand the roadway. If desired, the rivets 0 may be inserted with theirheads on the outside and these then serve themselves to save wear, whileas they cant the strips (a, the edges b remain as close to the ground asbefore.

The manner in which the device acts will be readily understood and hasalready been outlined in the above. As stated the strips (1 lie as closeas practicable to the ground and also to the vehicle wheel. Preferablythe beveled ends 7) are arranged to lie actually beneath the curve ofthe tire. W'hcn, then, the vehicle wheel moves laterally it promptlyengages upon the beveled end 7), not pushing this before it butdepressing it upon the ground and riding over it. Thus an intermediatesurface of different texture is interposed between the ground and thetire cover and the lateral slipping quickly ceases. l Naturally as soonas the wheel resumes a straight course, that is, rolls only in its ownplane, the strips a are released because their natural tendency is tohang from their supports just beside the wheel.

It will be quite clear that the invention is not by any means limited tothe precise details that have already been described. It would be quiteeasy to vary the method of suspension as well as the method of adjusting that suspension. Bdoreover it may be found desirable to insert insome part of the 1 suspension, say between the hook g and the spring, adevice for adjusting the length of the suspension so that the strips acan be brought a little nearer to or moved a little farther from theground if the apparatus requires adjustment. Another method of securingthis adjustment is to provide a buckle in the loop ofthe strap (Z. Theseand similar modifications and additions are, therefore, to be consideredwithin the scope of this application.

What we claim is:

l. The combination with a wheel of a vehicle, of a separate strip ofmaterial, means for supporting said strip at its two ends so that themiddle is near the ground, transverse strips, and means securing saidtrans verse strips at right angles to the suspended j strip in closeproximity to the wheel.

2. The combination wit-h a wheel of a vehicle, of a separate strip ofmaterial, means for supporting said strip at its two ends so that themiddle is near the ground, transverse strips with beveled edges, andmeans securing said transverse strips to the suspended strip in closeproximity to the wheel.

3. The combination with a wheel of a vehicle, of a separate strip ofmaterial, loops at the end of said strip, extensible means engaging withsaid loops for supporting said strip at its two ends so that the middleis near the ground, transverse strips, and means securing saidtransverse strips to the suspended strip in close proximity to thewheel.

4. The combination with a wheel of a vehicle, of a separate strip ofmaterial, means for supporting said strip at its two ends so that themiddle is near the ground, additional strips reinforcing said. suspendedstrip at its middle part, transverse strips, and means securing saidtransverse strips to the suspended strip in close proximity to thewheel.

5. The combination with a wheel of a vehicle, of a separate strip ofmaterial, means for supporting said strip at its two ends so that themiddle is near the ground, transverse strips, means securing saidtransverse strips at right angles to the suspended strip, and guidesengaging with said suspended strip to maintain it in close proximity tothe wheel.

6. The combination with the wheel and spring of a vehicle of a separatestrip of ma terial, pairs of plates secured upon the vehicle spring bybolts, and connections between said plates and the ends of the stripwhereby the strip is suspended close to the ground and to the wheel.

7. The combination with the wheel and spring of a vehicle, of a separatestrip of material, pairs of plates secured upon the vehicle spring bybolts, connections between said plates and the ends of the strip wherebythe strip is suspended close to the ground and to the wheel, and guidessecured to said plates and engaging with said strip to maintain it inposition.

8. The combination with a wheel of a vehicle, of a separate stripofmaterial, means for supporting said strip at its two ends so that themiddle is near the ground, transverse strips, means securing saidtransverse strips to the suspended strip in close proximity to thewheel, and studs attached to said strip between the transverse strips.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
